This is a high-resolution (3m) bathymetric grid with negative z values. The data were collected by the USF Center for Coastal Ocean Mapping with the Kongsberg Simrad EM 3000 multibeam system (Co-chief Scientists, David Naar and Brian Donahue). An Applanix POSMV 320 V3 system was used for real-time positions and vessel attitude (heading, pitch, roll, and heave). An AML (Applied Microsystems LTD.) SV plus was used to measure sound velocities in the water column. The data were collected in Fagatele Bay on November 10th, 2002 aboard a Motor Vessel Lady Ana.

Purpose:

This grid is a base layer for the purposes of visual overlay and comparison with other data sets around Tutuila and subsequent spatial analyses.
